It's held up fine, but it's hardly been played hard or ill used. Come back and ask me in ten years [grin]. If you do go down that route I melted candlewax into the threads and screwed the posts in so there was no possible way epoxy could impinge on the threads. That also means you can put the bridge in place while it's curing to ensure accurate spacing.
Are you aware of parcel tape? Very little and certainly not epoxy sticks to brown mylar parcel tape, so you can use it to ensure epoxy doesn't get on the main body. I might be inclined to stick the parcel tape onto masking tape though to minimise tape residue.
